This.
My original plans this season were one boy to one girl, so I didn't have any "who's your daddy" clutches. Well, snakes don't like "plans". Some of the boys decided they weren't going this year, my star boy got sick, and some others decided they wanted to have a go (Grew up quick and were ready for action) so we have a few girls where we paired 2 boys to because of lack of visual locks etc. Making sure of course that each male was significantly different (Mojo & Enchi x normal etc)
